Smart Meters Can Overbill By 582%

I can see overbilling by 5%, 8% maybe even 58% but DAMN...582%?!?!?

A team from the University of Twente and the Amsterdam University of Applied Sciences have published a paper demonstrating gross overbillings by smart energy meters, ranging from -32% to +582% of actual power consumption. Ironically, the overbilling is largely an artifact of power-saving features, which introduce line-noise that confuses the meters.
